Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3352H-1-104 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value (100 kOhms), power rating (0.5W), tolerance (±20%), adjustment type (side adjustment), physical dimensions (0.350" Dia x 0.350" H), termination method (PC pins), and mounting configuration (through hole). The primary distinction between the main part and its substitute relates to compliance certifications, specifically RoHS status and lead-free termination processing.

Parameter Comparison

Engineering Selection Recommendations

The 3352H-1-104LF serves as a direct functional equivalent to the 3352H-1-104, with the primary distinction being regulatory compliance status. Selection between these parts should be based on the following criteria:

For RoHS3-compliant applications: The 3352H-1-104LF is the appropriate choice, as it meets ROHS3 compliance requirements. This part is suitable for designs subject to European Union Restriction of Hazardous Substances directives or equivalent regional regulations.

For non-compliant or legacy applications: The 3352H-1-104 remains available and maintains active production status. This part is suitable for applications without RoHS compliance mandates.

For supply chain optimization: The 3352H-1-104LF currently maintains higher inventory levels (1477 units versus 996 units), providing improved availability for procurement planning.

Both parts maintain identical electrical performance, mechanical fit, and functional characteristics. The choice between them is determined by regulatory requirements and supply availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 3352H-1-104 and 3352H-1-104LF electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 100 kOhms resistance, 0.5W power rating, and ±20% tolerance. They function identically in circuit applications.

Q: What does the "LF" suffix indicate in the 3352H-1-104LF part number?

A: The "LF" designation indicates lead-free termination processing and ROHS3 compliance. This reflects the manufacturing process and regulatory status rather than functional differences.

Q: Can I substitute the 3352H-1-104LF for the 3352H-1-104 in existing designs?

A: Yes, provided your application does not have specific constraints against lead-free components. The mechanical fit, electrical performance, and mounting configuration are identical.

Q: Do these parts have different soldering requirements?

A: Lead-free termination (3352H-1-104LF) may require adjusted soldering parameters compared to leaded versions. Consult your manufacturing process specifications for lead-free component handling.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in bulk packaging. Verify specific packaging requirements with your procurement documentation.

Q: Which part should I specify for new designs?

A: For new designs, specify the 3352H-1-104LF to ensure compliance with current RoHS3 regulations and benefit from improved supply availability.
